4th NordicRAS Workshop on Recirculating Aquaculture Systems 2017

12-13 October 2017, Aalborg, Denmark

Field excursion 14 October 2017 

Organised by the Nordic Network on Recirculating Aquaculture Systems (NordicRAS) and the Technical University of Denmark (DTU Aqua)


Fish farming in recirculation aquaculture systems (RAS) is a fast-growing industry and the technology develops rapidly. An increasing number of large-scale RAS are constructed for production and on-growing of different species in both freshwater and seawater. There is, however, still a lot to be learned on how best to design and operate these systems including many new challenges arising when operating with saltwater.

On the 4th international NordicRAS workshop, farmers, operators, technology- and service providers, and researchers will present and discuss the current development, experiences gained, and recently achieved research results.

Workshop sessions

  • Session 1: Water quality in RAS
  • Session 2: On-growing of different species in RAS
  • Session 3: Waste treatment
  • Session 4: Particles and fish health in RAS
  • Session 5: Gases and online monitoring
  • Session 6: Saltwater RAS - organized by The Aquaculture Engineering Society (AES)

When and where

The workshop is held at Aalborg Congress & Culture Center. It starts 12 October 2017 at 10:00 (registration from 08:30 to 10:00) and ends 13 October 2017 at 15:00.


There will be a field trip on 14 October 2017 for a limited number of participants to state-of-the-art commercial RAS facilities. Unfortunately, all seats are already taken but you may send an e-mail to gsby@aqua.dtu.dk if you wish to be added to the waiting list
